Abstract
A power control driver of a BIOS has a function of changing a frequency of clock supplied to a CPU. According to the function of the power control driver, it is possible to set a normal mode for showing the CPU capability to the maximum and a power saving mode for preferentially taking power saving rather than the CPU capability. A power control utility program carries out the following power saving control. The program shifts a system to the normal mode when an AV application program operating an encoder and a decoder required for showing the CPU capability to the maximum is operating. In addition, the program shifts the system to the power saving mode when the program is not operating even if application programs other than the program are operating.
